Organ motion in pediatric high‐risk neuroblastoma patients using four‐dimensional computed tomography
PURPOSE/OBJECTIVE(S) High-risk neuroblastoma (HR-NBL) requires multimodality treatment, including external beam radiation of the primary tumor site following resection. Radiotherapy planning must take into account motion of the target and adjacent normal anatomy, both of which are poorly understood in the pediatric population, and which may differ significantly from those in adults. METHODS/M...
متن کاملFalse-positive MIBG scans with normal computed tomography imaging in patients with high-risk neuroblastoma.
TO THE EDITOR: Kushner et al investigate the most sensitive modality for early detection of relapse in patients with asymptomatic high-risk neuroblastoma who had previously achieved complete remission or very good partial remission. They demonstrate that iodine123 (I) metaiodobenzylguanidine (MIBG) scanning was the only positive surveillance scan in 27% of patients and conclude that IMIBG scann...
متن کاملOrgan Dose Measurement in Computed Tomography Using Thermoluminescence Dosimeter in Locally Developed Phantoms
Introduction: Organ dose estimation using thermoluminescence dosimeter (TLD) is known to be a standard, although many other methods, such as simulation software, optically stimulated luminescent dosimeters, and photodiodes are still in use. This study aimed at directly measuring mean organ doses to the selected organs in the head/neck, chest, and abdominal regions from four computed tomography ...
متن کاملEstimating and comparing the radiation cancer risk from cone-beam computed tomography and panoramic radiography in pediatric and adult patients
Background: This study aimed to estimate and compare the absorbed dose, lifetime cancer risk and mortalities due to cone-beam computed tomography (CBCT) and panoramic examinations on patients. Materials and Methods: The exposure factors were applied to 332 patients in two age groups (6-10, and ˃18-year-old). The dose-area product (DAP) values were measured for CBCT and panoramic radiographies. ...
متن کاملThorax organ dose estimation in computed tomography based on patient CT data using Monte Carlo simulation
Background: This study presents patient specific and organ dose estimation in computed tomography (CT) imaging of thorax directly from patient CT image using Monte Carlo simulation. Patient's CT image is considered as the patient specific phantom and the best representative of patient physical index in order to calculate specific organ dose. Materials and Methods: EGSnrc /BEAMnr...
